热带环境下的品种试验可以作为探索大豆高温生产力的一种途径。29个大豆品种分为5组与温带起源（日本和美国）和热带起源（马来西亚老，马来西亚现代和其他热带）在印度尼西亚万丹的热带环境中生长了两年，空气温度和日照长度的季节变化最小。温带品种在R1 ~ R5开花较早，花期较短。温带品种的种子产量为157 g m−2（平均温带品种），而热带品种为249 g m−2，这是由于豆荚、种子数量和TDW值较低。此外，在日本栽培品种中，与在其原产地生长的植物相比，发生皱缩和较小的种子大小是相当明显的。考虑到生育期的差异，计算了产量和相关变量的成熟度校正指数，以考虑入射太阳辐射量。所有供试品种的产量指数范围为0.49至1.48，日本品种的产量指数最低（0.67），其次是美国品种（0.87），而热带品种的指数平均值为1.05至1.20。虽然他们都是温带起源，日本品种往往表现出较低的指数比美国品种。TDW和节点数的变化趋势相似。温带品种的不良表现，即使在校正后，表明有一个适应热带环境的遗传变异的生长时间无关。此外，温带品种内有相当大的性能变化。
Cultivar tests under tropical environments could be an approach to explore soybean productivity under high temperature. Twenty-nine soybean cultivars divided into five groups with temperate origin (Japanese and US) and tropical origin (Indonesian-old, Indonesian-modern and other tropical) were grown for two years in a tropical environment at Banten, Indonesia, with minimal season-to-season variation in air temperature and day-length. Temperate cultivars were earlier in flowering and shorter in duration from R1 to R5. Temperate cultivars had a seed yield of 157 g m−2(mean temperate cultivars) compared to 249 g m−2(tropical cultivars), which was due to having lower values of pods, seed number and TDW. In addition, the occurrence of shriveling and smaller seed size compared to plants grown in their region of origin was considerably evident in Japanese cultivars. To account for the difference of growth duration, a maturity-corrected index for yield and relevant variables was calculated to consider the amount of incident solar radiation. The yield index for all tested cultivars ranged from .49 to 1.48, and Japanese cultivars showed the lowest yield index (.67), followed by US cultivars (.87), whereas tropical cultivars had index means from 1.05 to 1.20. Although they were both of temperate origin, Japanese cultivars tended to show a lower index than US cultivars. The tendency was similar for TDW and node number. The poor performance of temperate cultivars even after correction suggests that there is a genetic variation of adaptation to a tropical environment independent of growth duration. Additionally, there was considerable performance variation within temperate cultivars.
